摘要：An RFID detection system for determining the location of tagged items withinan interrogation zone. The system includes one or more printed circuit boards coupledto each other and placed within a region of the interrogation zone. Each printed circuitboard contains an antenna array having one or more antennas where each antennadetects the presence of one or more tagged items within a specific read zone in theregion. The printed circuit board also contains a multiplexer coupled to the antennaarray, where the antenna array and the multiplexer are provided on a substrate. Upon aninterrogation request from an RFID reader, a specific antenna can be activated andselected by the multiplexer and tagged items within the antenna's read zone areinterrogated. RF signals containing RF identification information are then transmittedback to the RFID reader where a host computer interprets the signals and determinesthe location of the identified tagged items.
